SWITCH FOR ELEVATED RAILROADS.

SPECIFICATION forming part of Letters Patent No. 227,996, dated May 25,1880.

Application filed April 20, 1880.

To all whom it may concern! Be it known that I, WM. WILLSHIRE RI- LEY, acitizen of the United States, residing in the city of Brooklyn, Kingscounty, and

State of New York, have invented certain new and useful Improvements inSwitches for Elevated Railroads, of which the following is aspecification.

The object of this invention is to provide a simple, safe, andconvenient means for switching upon elevated railroads, and speciallyadapted to that class of elevated railroads where a central rail and twoguard or guide rails are used, such as shown in patents granted to me in1876, numbered 173,240 and Myinvention consists in having a section ofthe elevated railroad constructed and arranged so that it may be swungto and from the main to the side track by having one extremity thereofsupported upon a substantial butt by a heavy pintle rigidly attached toits extremity, and in having the opposite or traveling end provided withfriction-rollers which bear 2 5 upon the upper surface of a suitablebedplate supported on bracketsor braces from the posts or columns, andin having the guard or guide rails supported at their respective ends byfixed brackets or braces under the same, so as 0 to prevent allpossibility of swaying or of the side rails deflecting at the joint withthe weight of the passing train.

Figure 1 represents a side elevation of my improved switch. Fig. 2 is aplan of the same, 3 5 showing the switch set to the main track. Fig. '3is an end view, showing the bed-plate for supporting the traveling endof the switchsection. Fig. 4 is an end view of the traveling end of theswitch, showing position of 40 rollers.

Similar letters of reference indicate corresponding parts.

In the case here presented, A represents a girder, and B B two guards orsafety guide- 5 rails, which are rigidly attached to and supported fromthe same by a series of A frames or braces, O C O, the whole forming acom- (N 0 model.)

%1ete section or span between the columns E is a heavy pintle, rigidlyattached to the girder A. This pintle is made or provided with twocollars, F F, and extends vertically through bearings G G on the butt orbracket H. This pintle is made of sufficientlength to insure perfect.steadiness to the switch structure; but in order to prevent thepossibility of deflection of either of the extremities of the safetyguide-rails I have provided a bearing,

I, for the support of the joints.

The opposite or traveling end of the switch isprovided with two or morefriction-wheels,

J J, which are housed, and have their bearin gs in the A-frame at itsextremity, and which bear upon the plane of the are or bedplate L,connecting the columns between the main and side track.

It will be observed that the extremity of the girder which abuts againstthe main central rail is made convex, so as to match the concavity atthe extremity of the fixed girder, and in order that the extremities ofthe guard or safety guiderails of the switchsection shall always remainin close contact with those of the main line, they are cut and setradial to the pintle E, and provided with wings KK at their extremities,so as to make the safetyguide continuous whether set for the main orside track.

Having thus described my invention, what I claim as new, and desire tosecure by Let- 8o ters Patent, is- I In an elevated railroad, thecombination of the independent swinging section A B G, having pintle Eand friction-wheels J J, with the fixed butt H, side wings or brackets,I I, and the supporting-arc L, rigidlyattached to the columns, the wholebeing constructed, arranged, and operating together in the manner andfor the use and purpose specified.
